The new PET Insert* for simultaneous high-field MR and PET imaging represents a culmination of Bruker Si detector innovations including unique continuous crystal technology with precise DOI detection, integration with SiPMs, and advanced electronics with full row and column readout. These innovations supply 0.7 mm resolution at Full Field Accuracy (FFA) and with 12% sensitivity that now extends to simultaneous PET/MR imaging with instruments up to 15.2 Tesla.
